Datasheet

Overview

This I2C digital temperature sensor is one of the more accurate/precise we've ever seen,

with a typical accuracy of ±0.25°C over the sensor's -40°C to +125°C range and precision of

+0.0625°C. They work great with any microcontroller using standard i2c. There are 3

address pins so you can connect up to 8 to a single I2C bus without address collisions. Best

of all, a wide voltage range makes is usable with 2.7V to 5.5V logic!
